Bacteriophage P4 is dependent on structural proteins supplied by a helper phage, P2, to
assemble infectious virions. Bacteriophage P2 normally forms an icosahedral capsid with T …

Assembly of the E. coli bacteriophage P2 into an icosahedral capsid with T= 7 symmetry is
dependent on the gpN capsid protein, the gpQ connector protein and the gpO internal …

The capsid protein of bacteriophage P2, encoded by the N gene, can assemble into
icosahedraf capsids of two possible sizes, with diameters of 60 and 45 nm, respectively …

Several of the structural proteins of phage P2 and its satellite P4 undergo proteolytic
processing during development of mature phage particles. Here, we report that uncleaved …

Bacteriophage P4 is a satellite virus of bacteriophage P2, which has acquired the ability to
utilize the structural gene products of P2 to assemble its own capsid. The normal P2 capsid …

Bacteriophage P22, a double-stranded DNA (dsDNA) virus, has a nonconserved 124-amino-
acid accessory domain inserted into its coat protein, which has the canonical HK97 protein …

Bacteriophage P2 encodes a scaffolding protein, gpO, which is required for correct
assembly of P2 procapsids from the gpN major capsid protein. The 284 residue gpO protein …

The double-stranded DNA bacteriophage P4 has a T= 4 icosahedral arrangement of the
gpN capsid protein derived from the P2 helper phage. The precursor procapsids in addition …

The formation of many double-stranded DNA viruses, such as herpesviruses and
bacteriophages, begins with the scaffolding-protein-mediated assembly of the procapsid …

An interesting feature of the bacteriophage P2–P4 system is the switch in size between a
large P2 (60 nm) and a small P4 (45 nm) capsid. We have investigated whether the protein …
